Server Board S5500WB uses the BIOS recovery to repair the system BIOS from
flash corruption in the main BIOS and Boot Block. This 3-pin jumper is used to reload the
BIOS when the image is suspected to be corrupted. For instructions on how to recover the
BIOS, refer to the specific BIOS release notes.

8.4 Reset BIOS Configuration (J1B4)

NVRAM region of the BIOS flash since the previous generation. The BIOS checks during
boot to determine if the data in the NVRAM must be set to default.

Clearing the CMOS
1. Power down server. Do not unplug the power cord.
2. Open the server chassis. For instructions, refer to your server chassis
documentation.
3. Move the jumper (J1B4) from the default operating position, covering pins 1 and 2,
to the reset/clear position, covering pins 2 and 3.
4. Wait five seconds.
5. Remove AC power.
6. Move the jumper back to default position, covering pins 1 and 2.
7. Close the server chassis.
8. Power up the server.
The CMOS settings are now cleared.
Note: Removing AC Power before performing the CMOS Clear operation causes the system
to automatically power up and immediately power down, after the procedure is followed and
AC power is re-applied. If this happens, remove the AC power cord again, wait 30 seconds,
and re-install the AC power cord. Power up system and proceed to the <F2> BIOS Setup
Utility to reset the preferred settings.
